VISCOSITY AND THERMAL CONDUCTIVITY OF REFRIGERANTS MIXTURE R32/R125

Abstract

Equations describing viscosity and thermal conductivity experimental data of alternative refrigerants mixture R32/R125 are compiled. Equations represent refrigerants mixture viscosity and thermal conductivity dependence from temperature, density and composition. Providing possibility to calculate mixture viscosity at temperature ranging from 222 to 423 K at a pressure up to 7,7 MPa and mixture thermal conductivity at ranging from 213 to 405К up to 30 MPa. Standard and maximum deviations of the experimental values from calculated are equal 2,3% and 5,8 % for viscosity and 2,4 % and –4,9 % for thermal conductivity.
